IncGamers has word on the launch of signups for World of Warcraft
players interested in beta testing the Wrath of the Lich King expansion
for Blizzard's MMORPG, saying this is as simple as opting in to the beta test
via your account page on the website, though apparently at the moment the
European Account Page has the
opt-in link, but it has not yet appeared on the
US Account Page.
Update: US Signups are underway as well.
